Alicia Marie emerges from the scenery as a green “Orion slave girl” from the original “Star Trek” series as she takes a selfie during the 16th annual Official Star Trek Convention at the Rio All-Suite Hotel and Casino last year. Cosplay and a costume contest are highlights of the show, along with panel discussions and autograph sessions with many of the stars in the galaxy of the “Star Trek” franchise. This year’s show engages Aug. 1-5 at the Rio. – Photo by Sam Morris/Las Vegas News Bureau
